PUMPING APPARATUS.

SPECIFICATION formingvpart of Letters Patent No. 227,528, dated May 11, 1880.

Application filed September 13, 1879. I

To all whom it may concern: I

Be it known that I, WILLIAM V. HENRY, of Sacramento, in the county of Sacramento and State ofOalifornia, have invented a new and Improved Pumping Apparatus, of which the following is a specification.

The object of my invention is to furnish simple and durable pumping apparatus, especially adapted for raising large quantities of water for irrigating purposes and for draining mines.

The invention consists in pump-barrels suspended from a walking-beam and reciprocating upon a valved piston-head that is held upon a fixed rod. The barrels are fitted with -check-valves, and the whole apparatus constitutes a balanced force-pump that may be fitted in open or bored wells and driven by horse, wind, or steam power.

The apparatus is shown in the accompanying drawings, wherein-- Figure 1 is a cross-section, .Fig. 2 is a section showing the piston-chamber in larger size.

. Similar letters of reference indicate correspondin g parts.

The platform at A represents the surface of the ground in which the wells are dug or bored. With an open well the barrels a a both enter the well, and with bored wells, which are usually made in pairs, the barrels a extend into the adjacent well-tubes.

B is a standard carrying the beam 11. The barrels a are suspended by arms I) from the beam b, and are formed at their upper ends with nozzles 01 for the discharge of the water.

To the lower end of each barrel a a pistonchamber, f, is connected bya screw or flanges and bolts, and at the joint is a check-valve, g,

opening upward.

Upon the standard 13 is fixed a cross-bar, e. To thisbar e the piston-rods c are rigidly connected, and the rods 0 pass down through the barrels a to the bottom of the well. Upon the lower ends of v rods 0 there are spiral springs or spring-arms k, which act to retain the rods and barrels in place against lateral movement and relieve shocks upon the piston.

Upon each rod 0, within the piston-chamber f, is fixed a valved piston-head, l, the valves opening upward. The packing of head 1 is, preferably, a cup-leather secured in place at the inside of the piston by a ring that will be held in place by the pressure of water.

In bored wells the spring-arms is will occupy a position in the tubing as shown at h h in Fig. 1, the short tubes h representing the tubing at the bottom of such well.

In operation the beam 1) will be operated by suitable power, and by the reciprocation of the barrels upon the fixed heads I the water will be raised alternately in the barrels by pressure without suction. The stroke can be varied without alteration of the parts. The piston-chambers will be submerged in the water, and in deep mines reservoirs will be arranged at intervals, and the water raised in succession from one reservoir to a higher one, the separate apparatus being connected and driven by one motor, so that but little increase of power or strength of barrels will be necessary to elevate the water a long distance.

By working the pumps in pairs the whole apparatus can be nearly balanced, and but" little power will be needed to raise large quantitles of water. For raising water in large quantities the piston-chamber should be of greater diameter than the barrels a, in which case the barrels .a will act as delivery pipes or tubes for the water.

The retaining device It may be made in the form of spiral springs, and, while serving to hold the rod 0 in position, give elasticity and prevent injury by sudden shocks.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination of the walking-beam b, the arms or links I), the vertically-reciprocating barrels or tubes a, provided with the nozzles d, check-valves g, and piston=chambers f, and the stationary piston -rods 0, passed through the said barrels or tubes and provided with the piston-heads l,,substantially as and for the purpose set forth.

2. 1n pumping apparatus, the combination, with the fixed piston-rod c and head I, of the springs or arms In, attached on the lower ends of the piston-rod, substantially as and for the purposes set forth.

WILLIAM v. HENRY.
